Обсуждение: odbc version
More on the continuing saga of our problem... So, in our client application, we are getting today's date returned for time fields. After working with someone offline and sending logs, it turns out that we are running ODBC 3.0 and the pgsqlodbc driver is not compatible with that version. I've tried to find on the website (odbc.postgresql.org) where it says this but can't seem to find this information. Anyway, I downloaded the trial pgsql driver for ODBC 3.0 and installed it (manually per instructions). Our client program now gets a segmentation violation with this driver. So, my questions are: 1) When will a final pgsql driver for ODBC 3.0 be out? 2) Is there a way to uninstall ODBC 3.0 and install a supported version of ODBC (supported by this current psql driver)? If so, were can I find this "older" version of ODBC? We are running this on Windows 2000.

For example I can see both PostgreSQL and PostgreSQL30 driver using ODBC DatasSource Administrator. regards, Hiroshi Inoue
Then I am completely confused. I thought that the pgsql driver does not support ODBC 3.0. Isn't that installed with the Windows? Isn't that a seperate package? Don't I need to get a previous version of that? My understandnig is that there are several elements involved here: 1) Client program, 2) ODBC, 3) postgresql driver Which of these is what you indicated was ODBC 3.0? Isn't it #2? If so, then is there a way to replace that with a previous version? It is with the trial postgresql driver (#3) that is compatible with ODBC 3.0 (#2) that we get the segmentation violation when trying to use it in our client (#1). Or am I way off here? Thanks, L.

Isn't it #2? Yes. However the driver is a trial one and it seems dangerous to replace the current driver. So I separated the ODBC 3.0 driver from the current driver. From ODBC POV they are different drivers and you have to create new DSNs for the trial driver and so on ... regards, Hiroshi Inoue
Forgive me, but I think either you are missing my point or I am missing yours. I need to ask some more questions, but I will do it one at a time... Is the trial driver (from the url you gave me) a trial *Postgresql* driver for use with ODBC 3.0?

There are 2 drivers at the url. psqlodbc.dll the newest ODBC 2.50 driver(not a trial one). psqlodbc30.dll ODBC 3.0 driver (a trial one which was never announced to be offically supported). Judging from your ODBC trace log you sent me, your application is completely a ODBC 3.0 one. So I'd like to see how my trial ODBC 3.0 driver works with you app. regards, Hiroshi Inoue

So I'd like > to see how my trial ODBC 3.0 driver works with you app. Yes. I agree. The trial ODBC 3.0 driver generates a "segmentation violation" when we try to use it. So, my second question is, is it the Microsoft ODBC that is version 3.0? Thanks, Laurette

Please remember there's always an ODBC driver manager between your app and the ODBC driver. Though your app calls many ODBC 3.0 specific APIs, the driver manager translates them into ODBC 2.50 APIs as much as possible when you are using ODBC 2.50 driver via your DSN definition. My trial ODBC 3.0 driver implements many(? at least not all unfortunately) of ODBC 3.0 specific APIs and the driver manager doesn't have to translate them. regards, Hiroshi Inoue
